Protection of shearing and crushing points for large and heavy power-operated facilities such as hangar doors, theatre stages or automated guided vehicle systems (AGVs) pose a particular challenge because they have a high moment of inertia and long stopping distances.
Our safety bumpers HSB which are able to absorb longer braking distances serve to protect against these kinds of hazards. They operate according to the highly effective and reliable normally closed contacts principle and ensure that the automatic actuation is stopped immediately upon contact, e.g. with part of a body.
What is a bumper?
Safety bumpers are contact-sensitive devices that detect contact with a person or part of a person's body. Should a bumper register a contact or an obstacle, the automatic drive of the machine is immediately stopped.
While safety edges are fitted with one sensor, bumpers can be equipped with several signal transmitters and also feature an actuating surface that is usually over 80 mm.
Safety bumpers are therefore particularly effective in protecting the shearing and crushing points of large and heavy powered equipment. Here is just a small selection of the machines and systems that use our safety bumpers HSB:
- Theatre stages
- Hangar doors
- Automated guided vehicle systems (AGVs)
- Lifting and work platforms
Functionality and structure
Our bumpers consist of a foam housing with the Haake contact chain installed inside. The foam housing is covered with a highly abrasion-resistant elastic polyurethane coating. There are additional materials and solutions available to suit applications involving harsh environmental conditions (e.g. aggressive media).
The Haake contact chain consists of electrically conductive contact rolls and intermediate insulating elements connected in series. These are arranged alternately along an expander cord. With the help of pre-tension force, the contact rolls are pressed together; and the closed circuit is completed.
When activated, at least one of the contact roll pairs is isolated with the wedge-shaped insulating spacers. This breaks the closed circuit. Conversion of the output signal is therefore unnecessary, as a break contact signal is transmitted directly to the relevant emergency stop module of the secured machine.
